Maximo Lobato signs in at Dr. Carlos Serrano's clinic in Petare, one of the largest and most dangerous slums of Caracas. Lobato has high cholesterol and Dr. Serrano prescribed Lipitor and two other drugs. He says that he does not have enough money to buy all three medicines and will probably only buy Lipitor right now. Pfizer is trying to increase their market share in the slums and are targeting clinics, hospitals and pharmacies, sending sales representatives to the far reaches of the slum.
